This 1 invention relates to washing and cleaning equipment and more particularly ato mops operating -.on a vacuum principle.
' 'The conventional method for drying up: water :from -a:fioor -beingwashed with water or "other liquids .consists :generally in .the use'o'f :a cloth 01: rope1mop'on:the :end of a handle ora mopping cloth'alone, which is relatively dry-at the beginning and :absorbs the water into I itself until about saturated. Then :the mop. is wrung: or squeezed so the wateris:ejectedand the rmop made relatively d y a ain an'drreadyforbreuse; .The process is an inconvenient one--no--matter how well done. It takes timeand: effort to wring :out thewvater and-the mop-becomes soadirty and saturated with water after a little use thatri't .does not remove =asmuch-of the-dirtand water as it: should; The operator thereforehasin: most cases, to clean upagain a after "a first mopping,
with clean water and a new or' washed out and dried mop. The mop when relatively dry, ab-
.sorbs-the water "by-capillary action. The mop decreases in its'powerof absorptionasit -be- :comes'more orless filled .by the water drawnup in itwandholds-it in suspension in'a-very loose manner. In fact some of thewater usually drops on the floor'from the-mopas it is raised orcar- ;riedto thebucket intowhich-the water is to be.- squeezed. The drops of water'then :have to .besmopped up. in another mopping. The several additional i moppings, together with :the. squeezf .ing, and thezseveral handlingsand carrying of :the mop to and from the bucket usedwith the .mop make the workye-ry inconvenientystrenuous and-long. Itis-thereforean-object of. this invenmopping up-the water-used-in the washing of floors and similar surfaces, that will avoid one or more of'the disadvantagesand'limitations of the prior art.
Another object of the .presentinvention is to I provide a new and improved mechanical mop that will draw up the Water'orliqui'd used for washing a surface effectively and quickly.
A further object of the herein described inven- 1 tion is to provide a new and. improved mechani-- securely together, and be provided with a con-;."
"35 tion lZO DIOVldG ,a-new andimproved device-for venient *an'd clean arrangeme'm for discharging itin a controlled manner.
Other objects will: become apparent as the invention is more fully set forth.
For A a' better understanding of the invention and the objects 'thereof; reference is ma'cleto the- =accompan-ying drawings and the description fol- "lowing. These together detail a particularform "of the invention byway of example'for'illus'trating its principles of construction-end operation,
while-the appended claims indicate the' scope of the invention.
Inthis invention; thestructure-employedoper- -ates under a vacuum -principle,-in thatit-"uses a nozzle connected with a container, whichis run overto -suck upthe water or Iiqui'd'to be: removed The container and nozzle are cause damage thereto.

Similar reference numerals refer to. the-simi- 'lar-parts-throughont the drawings.
Referring to Figure "1 inparticular;avacuum cleaning machine structure I0 is shown in dotted outline as conventional equipment which has its flexible hose I I connected with a tubular handle l2 by a coupling l3. The handle I2 is preferably made as indicated and is provided with an ex- 3 tension tube 16 that fits through a stufiing box [4 into a, receptor tank i5, which is adapted to hold the water or liquid i1 raised from a surface during washing and drying process. The extension tube has a collar l 8 mounted peripherally on it, and serving as an abutment against which a coiled spring [9 presses at one end while its other end contacts the stufiing box end of the tank I5, This keeps the liquid from running out of the tank until released. The end portion of the tube disposed in the interior of the tank is surmounted by a liquid and air separator 2|; This diverter is attached to the lower end of the tube [6. The lower end of the diverter is connected to a nozzle tube 22 of similar interior and exterior dimensions as the tube It. It oflfers a passage for the flow of liquid from a nozzle 23 into the tank IS. The tube 22 is slidably held in the central collars 24 of spiders 25 rigidly at-' tached to the interior surface wall of the tank IS. The tubes [6 and 22 with the interconnected separator 2! are rigidly connected with one another, so that the telescoping or pulling of the tube It through the stufiing box 14 will move them all together until the lower end tapered portion of the tube 22 fits in the angular portion 5i of the hose 2'! at the lower end of the tank 15, or lifted out therefrom for emptying the tank as the case may be. A rubber or plastic hollow gasket 39 on the exterior of the portion 26 serves to make a tight joint. The nozzle 23 is held on the nose 2'! by a coupling 28. The nozzle may be of several contours but that of a spreaded design as indicated in Figure 2 is preferred in this embodiment.
The separator 21 is tapered from each collar end-portion 29 and 30 respectively towards the middle, as shown, with an inverted cone 3| situated internally to act as barrier or bafiie to the liquids sucked up through the tube 22 into the diverter and separate the air therefrom. The collars 29 and 30 are supported on spaced straps 32 and 33 welded to the cone 3| so the liquid from the tube 22 can spill out directly into the tank [5 without passing beyond the barrier cone 3!, while the air creating the vacuum or sucking action in the tube will pass freely into the tube 16 free from the liquid, and back into and through the vacuum machine I0. In this instance the tube 22 is inserted tightly into the nose 2'! so all the suction is on the nozzle and there is no leakage of liquid out of the tank through the nose 21'. When the tank is full enough to require the emptying of the water from it, the handle I2 is pulled upward by the operator with one hand against the resistance of spring l9, while his other hand resists the pull on the tank or receptor 15 by holding the tank handle 34, until the tube end portion 26 is lifted out of the nose 21, as shown in Figure 6 and the water is allowed to flow out of the nozzle into a bucket. During the dumping of the water, the vacuum machine is preferably stopped, so there will be no tendency for the water to hold or stay in the tank during this dumping action under a vacuum tension.
The use of the vacuum for sucking up the washing liquids provides a clean and effective method for their removal from the floor and is done expeditiously and with the complete ;re-
4 moval of the dirt with them, and avoids the necessity of repetition in the process in the same area or recleaning as required by the usual of cloth or rope mop method.
While but one general form of the invention is shown in the drawings and described in the specification it is not desired to limit this application for patent to this particular form, as it 'is' appreciated that other forms could be made that would use the same principles and come within the scope of the appended claims.
Having thus described the invention, What is claimed is:
1. An apparatus of the class described comprising in combination, a suction nozzle, a receiving tank communicating therewith and secured thereto at its bottom, conduit means within said tank communicating with a source of suction, the outer periphery of said conduit means normally blocking both ends of the tank, said conduit means having an opening in the receiving tank intermediate the ends of said conduit means, means in the aforesaid opening for diverting liquid sucked up through the nozzle and directing the liquid into the receiving tank where it is trapped,.said conduit means being slidable within said tank to move the end of the said conduit means adjacent the nozzle away from the bottom end of the tank to place the tank in direct communication with said nozzle, whereby the liquid trapped in the tank may flow outwardly therefrom through the nozzle.
2. An apparatus as set forth in claim 1, wherein the means for diverting liquid include a baiiie to separate air from liquid sucked within said tank.
3. An apparatus as set forth in claim 1, including a spring normally opposing sliding movement of said conduit means away from the bottom end of the tank.
4. An apparatus of the class described comprising in combinatioma suction nozzle, a receiving tank communicating therewith and secured thereto at its bottom, piping within said tank communicating with'a source of suction, said piping comprising a lower section normally abutting and peripherally blocking the bottom end of said tank, and an upper section extending through theupper end of said tank and peripherally blocking said end, bafile means intermediate said piping sections, said piping being slidable within said tank whereby the lower piping section may move away from the bottom end of the tank, a spring coiled about the upper piping section and abutting the upper end of the tank, and an abutment for the opposite end of the spring carried by the upper piping section.
